Technical Field

The invention relates to the technical field of ship energy conservation and emission reduction, in particular to a watertight device for a pipe tunnel of a ship lateral thruster.

Background

In the ship navigation technology, in order to reduce the resistance when a ship is directly navigated, the technology of additionally arranging side push pipe tunnel sealing covers at the two ends of a ship side push tunnel can be adopted. However, most ships are still not willing to equip the side push pipe tunnel sealing cover because the existing side push pipe tunnel sealing cover technology is low in cost-efficiency ratio, single in performance, high in failure rate and large in occupied space of an actuating mechanism and cannot be arranged. Meanwhile, in the existing side push tube tunnel sealing cover technology, a grid plate arranged axially is a common technology, such as chinese patent CN201120036732.8, CN 201420449272.5. The grid plate is arranged at the tunnel opening through a power shaft, and the power shaft penetrates through the tunnel wall to enter the cabin and is matched with the power device. And the power shaft is in watertight connection with the tunnel wall. However, a common trouble of this technique is that, this kind of side-push tube tunnel capping technique because most of blades occupy the tube tunnel inner space after opening, and its pivot and connecting rod formula starting and stopping mechanism also all install inside the tube tunnel, therefore can't install the operation in the side-push tube tunnel of the short high-speed ocean transport boats and ships (such as container banning wheel, etc.) of ship bottom section line shape angle great thus cause the tube tunnel. Another kind of puzzlement is, because the automated control system design of current side push pipe tunnel closing cap is not advanced enough, including the grid plate structure that a plurality of blades are constituteed is complicated, single spare part is numerous, and side push pipe tunnel closing cap is the invisible equipment of visualing below the waterline again for a long time submergence, can't emergent get rid of also can't confirm its exact state when making side push pipe tunnel closing cap in use often takes place equipment trouble, lead to whole grid plate system can't move and make the lateral thruster can't use. Still another kind of puzzlement is, grid tray formula closing cap is the structure that permeates water, can't drain the sea water in the side push pipe tunnel, and maintainer can't get into the side push pipe tunnel when boats and ships are berthhed on water and overhaul the side propeller, consequently if will overhaul the side propeller then still need make boats and ships shut down and go into dry dock, has caused the loss of operation and has paid the dry dock expense of large amount in addition from this. The other common trouble is that the side push pipe tunnel sealing cover in the form of the grid plate is still permeable, the flowing impact of seawater in the grid plate gap still causes certain resistance to the ship when the ship sails, and the energy-saving and emission-reducing effects of the side push pipe tunnel sealing cover are not optimal. Another common problem associated with this is that although watertight connections are used between the power shaft of the grid-type cover and the tunnel wall, the power shaft still remains in motion as a rotating shaft seal (i.e., shaft seal), and when the seal fails, seawater may still leak into the ship's cabin, which may cause the risk of cabin water ingress. In addition, the following structure of the waterline of the ship often breeds the attached marine organisms (including algae and shellfish), and the pervious grid plate type side push pipe tunnel sealing cover runs by adopting a rotating shaft pushing mode with smaller torsion, and the rotating shafts are numerous, so that after the marine organisms are bred at the inner side, the outer side, the rotating shafts and other parts of the grid plate, the rotating shafts are often blocked due to the smaller torsion, and the serious problem that the blades of the pipe tunnel sealing cover cannot be opened/closed or cannot be completely opened/closed is caused.

There is also a form of watertight cover which has not been put into practical use at present, for example, in the Chinese patent201621458486.4The plate grid type cover plate has the advantages that part of troubles of the plate grid type cover plate can be eliminated theoretically, but the plate grid type cover plate needs to be provided with complex opening and closing actuating mechanisms in the side push pipe tunnel, the size of the actuating mechanisms and the required operation space are very large, and the mechanisms cannot be accommodated and operated in the pipe tunnel with the short bottom of an ocean transport ship, so that the feasibility is low, and the plate grid type cover plate has no successful practical application case so far.
